Teen Pleads Guilty To Assault Of Security Guard At Good Life Perth

18-year-old Martin Fulton has pleaded guilty to the assault of a security guard at this year's Good Life Festival in Perth. 

As ABC reports, he also admitted to charges of trespassing at the festival and was released on bail. He'll be sentenced next month. 

The news surfaced via social media back in March when a mobile phone video went viral of Fulton kicking security guard Michael Rigby in the head repeatedly at the under-18s festival. At the time, Rigby was trying to detain another festivalgoer when Fulton jumped into the altercation.

After the incident, 56-year-old Rigby told 9 News that "the actual impact rocked my whole head so all the muscles in my neck are all sore and it runs down to my shoulder".
